Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16200, here are decompositions:

7 + 16193 = 16200
11 + 16189 = 16200
13 + 16187 = 16200
17 + 16183 = 16200
59 + 16141 = 16200
61 + 16139 = 16200
73 + 16127 = 16200
89 + 16111 = 16200

Showing the first eight; more decompositions exist.
